Abstract

A method of producing a tire with a simplified operation and a high productivity, for improving the lateral rigidity and the steering stability performance of the tire. An annular laminated body as a reinforcing layer in the side surface area of the tire is formed by spirally winding and laminating a ribbon of an unvulcanized rubber embedding a thin gauge and embedding short fibers with a desired orientation. The annular laminated body is applied at a position corresponding to the side surface area of the tire, between the outer rubber and the inner liner rubber, upon formation of a green tire for the tire.
